PTFE Rov Qab Rings

Kev Piav Qhia Luv:

PTFE Back-up Rings yog cov khoom tseem ceeb hauv cov tshuab kaw siab, tsim los txhawb cov foob tseem ceeb xws li O-rings thiab tiv thaiv kev tawm hauv qab kev ntxhov siab heev. Tsim los ntawm polytetrafluoroethylene (PTFE), cov nplhaib no qhia txog kev tsis muaj tshuaj lom neeg zoo heev, tiv taus yuav luag txhua yam tshuaj lom neeg xws li cov kua qaub muaj zog, cov alkali muaj zog, cov kuab tshuaj organic, thiab cov pa roj corrosive. Lawv cov coefficient sib txhuam qis heev thiab qhov ruaj khov zoo kawg nkaus ua rau muaj kev ua tau zoo hauv kev siv dynamic nrog qhov kub ntawm -200 ° C txog + 260 ° C. Lub zog compressive siab ntawm cov khoom siv thiab cov yam ntxwv tsis deformable ua kom muaj kev faib khoom zoo tshaj plaws, tiv thaiv cov foob elastomeric los ntawm kev tawg lossis kev puas tsuaj thaum muaj kev hloov pauv siab. Nrog rau cov yam ntxwv tsis lo thiab FDA / USP Class VI ua raws li qhov xav tau, PTFE Back-up Rings siv dav hauv cov lag luam tseem ceeb xws li cov khoom siv roj thiab roj av, cov tshuaj ua cov tshuaj reactors, cov tshuab hydraulic, thiab cov tshuab tshuaj uas xav tau kev ua haujlwm tsis muaj kuab paug. Lawv kev sib xyaw ua ke ntawm kev tiv thaiv tshuaj lom neeg thiab kev ua kom lub zog ua rau lawv tsis tseem ceeb rau kev tswj hwm kev ruaj khov ntawm cov foob hauv cov chaw ua haujlwm hnyav.

Cov Cim Npe Khoom

PTFE Back-up Rings yog dab tsi?

PTFE (Polytetrafluoroethylene) Cov Nplhaib Rov Qab yog cov khoom tseem ceeb hauv cov txheej txheem kaw, tsim tshwj xeeb los tiv thaiv kev rho tawm thiab kev hloov pauv ntawm cov foob thawj zaug hauv qab qhov siab thiab qhov xwm txheej hnyav. Cov nplhaib no muab kev txhawb nqa tseem ceeb rau O-rings thiab lwm yam foob elastomeric, ua kom ntseeg tau tias muaj kev ntseeg siab thiab kev ncaj ncees mus sij hawm ntev hauv cov ntawv thov kev lag luam uas xav tau.

Cov yam ntxwv tseem ceeb ntawm PTFE thaub qab Rings

Kev Tiv Thaiv Tshuaj Zoo Tshaj Plaws

PTFE Backup Rings muaj npe nrov rau lawv cov tshuaj lom neeg tsis muaj zog, muab kev tiv thaiv tsis zoo rau ntau yam tshuaj lom neeg, suav nrog cov kua qaub, cov hauv paus, cov kuab tshuaj, thiab roj. Qhov no ua rau lawv zoo tagnrho rau kev siv hauv cov chaw muaj zog heev uas lwm cov ntaub ntawv yuav lwj.

Ntau Qhov Kub Dav Dav

PTFE tuaj yeem ua haujlwm tau zoo thoob plaws ntau qhov kub thiab txias, txij li qhov kub cryogenic mus txog ntau dua 500 ° F (260 ° C). Qhov kev hloov pauv no ua kom ntseeg tau tias PTFE Backup Rings tseem ua haujlwm tau zoo thiab txhim khu kev qha hauv ob qho tib si kub thiab txias heev.

Kev Sib Txhuam Qis

PTFE muaj qhov sib txhuam qis heev, uas txo qhov hnav ntawm cov khoom sib txuas thiab txo qhov poob zog. Cov yam ntxwv no kuj pab txo qhov kev pheej hmoo ntawm kev galling thiab seizing, ua kom ntseeg tau tias kev ua haujlwm du txawm tias nyob hauv cov khoom hnyav.

Muaj Zog Kho Tshuab Siab

PTFE Backup Rings tau tsim los kom tiv taus kev ntxhov siab loj heev thiab kev nyuaj siab. Lawv txoj kev tsim kho kom ruaj khov tiv thaiv kev rho tawm thiab kev hloov pauv, yog li ua kom zoo dua qhov kev ua tau zoo thiab lub neej ntev ntawm lub kaw lus sealing.

Tsis muaj kuab paug thiab ua raws li FDA

PTFE yog ib yam khoom uas tsis ua rau muaj kuab paug, ua rau nws tsim nyog rau cov ntawv thov uas qhov huv thiab kev dawb huv yog qhov tseem ceeb, xws li hauv kev ua zaub mov, tshuaj, thiab kev lag luam semiconductor. Ntau lub PTFE Backup Rings kuj muaj nyob rau hauv qib FDA-ua raws li, kom ntseeg tau tias lawv ua tau raws li cov qauv kev cai nruj.

Cov ntawv thov ntawm PTFE Backup Rings

Cov Tshuab Hydraulic thiab Pneumatic
